2018 Retirement Account and Related Limits

The IRS and the Social Security Administration recently announced retirement plan contribution limits and other related limitations for 2018 to reflect cost-of-living adjustments (COLA). The 2018 limits are outlined below. Several are unchanged from 2017.

Definition of “Highly Compensated Employee”: The limitation used in the definition of “highly compensated employee” remains unchanged at $120,000. The IRS generally defines a “highly compensated employee” as an individual who:

  • Owned more than 5% of the stock or other interest in the employer at any time during the current year or the previous year, regardless of how much compensation that person earned or received, or
  • For the preceding year, received compensation from the employer of more than $120,000 (if the preceding year is 2016, 2017 or 2018), and, if the employer so chooses, was in the top 20% of employees when ranked by compensation.

Catch-up Amount: The IRS permits individuals who are 50 years of age or older to make catch-up contributions (amounts vary by plan) to their 401(k) and/or individual retirement accounts. The Economic Growth and Tax Relief Reconciliation Act of 2001 created this provision to give employees the opportunity to save more money for retirement.

1 Or, if less, 100% of taxable compensation

2 For individuals age 50 or older

3 The maximum amount of wages in 2018 that is subject to the 6.2% Social Security tax

4 Or, if less, 100% of average compensation over the three-year period during which the participant had the greatest aggregate compensation from the employer

5 The annual ceiling on employee compensation that can be used to calculate employee-deferral and employer-matching contributions.
